Frequently Asked Questions

Q) Help!
I am breaking a lot of needles and the tension is getting too tight on
its own while stitching and causing the thread to break. I am learning
the machine for two weeks. Is it so sensitive too wools, cottons, and
fleece that this would make such a major difference in the stitching -
breaking needles, breaking thread?

(A) It may not be tension that is causing the problem with your portable
blindstitch. If you have broken needles it has probably left some
needle burrs in the thread and needle path that need polishing off with
fine emory cloth (crocus) before sewing again.

Start with a new LWx6T needle without thread or fabric. Watch the
needle as you turn the hand wheel. If there is needle deflection,
reduce the penetration dial until there is no needle movement. If there
is needle deflection caused by burrs, they must be polished off. Check
the looper tip and two arms for any needle burrs and polish off. If
there is needle deflection caused by the needle track lifting the
needle, lower the track very slightly with the screws on the side of
the black metal bracket above the needle.

Finally, Back off on the tension dial and retighten while you are
sewing with a light strong thread and light to medium weight fabric,
until you get the correct tension without loops. If tension is too
tight it will push the thread up so it is not all the way down between
the tension discs where it belongs.

(Q) I can't understand how to finish off at the end. It
always unravels. I have read the manual and it seems simple but I
apparently just "don't get it." Any help would be appreciated.

(A) At the end of the blindhem seam, position the needle all the way to the left, then use the knee lift to remove the fabric and jerk on the fabric at the same time. That will tie off the tread and break the thread at the
needle without bending the needle. You can weave the thread tail back into the stitches or cut it off. Before the above procedure, you could also turn the handwheel counterclockwise for a few stitches, then come back to the end of the seam and repeat the first procedure above.

You need to change the correct size needles. There are two types of needles. One with cylindrical head and other with cylindrical head with flat surface on one side.
The other problem may be the position of the direction of the thread passing through the needle.
The third problem may be move your needle position one millimeter up or down and tighten it and check.
Please follow through these 3 steps one by one. You can fix the problem

the gear or part that holds the needle position in place may eitherbe getting jarred or is worn,,try using a different threadThe needle thread breaks
1. the needle thread is not threaded properly
2. The needle thread tension is to tight
3. The needle is bent or blunt
4. The needle is incorrectly inserted
5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew
6. the threads were not drawn to the rear after sewing
7. The thread is either to heavy or to fine for the needle

also try adjusting the top thread tensionas far as the bright spot, the display could be going out.

sometimes the repair person does not check the machine to see if the machine is working correctly, because they would have to charge more and some don't so you have to bring the machineback more often and that makes them more money.

For the cover stitch, only use a size 90 needle. Depending on the type of knit, use a ball point or stretch needle. The 936 uses standard sewing machine needles, so you can switch needles with the type of fabric, just like with a sewing machine.

If there is no noise, like the machine is calibrating or setting up, then more than likely the fuse on the transformer has blown. If the needle motor and feed motor make their usual noise and the lights come on but the screen won't come on, chances are a connection inside the machine is your problem. If the cable from the display screen becomes unplugged, the machine will "start up" but nothing will be displayed on the panel. If when you turn on the machine, you touch the screen and hear the "click" sound the screen makes then its a problem with the display screen only. (there are 2 screens, the one you touch your finger with is the touch screen and the one behind it displaying the picture is the display screen.)
